APPARATUS FOR HEATING AIR FOR THERAPEUTIC OR OTHER PURPOSES. I

SPECIFICATION forming part of Letters Patent No. 608,928, dated August 9, 1898.

Application filed lml 21,1897. Serial No. 662,835. (No model.)

To 11/7/7 whom it may concern: 7 Be it known that 1, WILLIAM TAYLOR, M.

ll, F. R. G. I. E, a subject of the Queen of- (Yfreat Britain and Ireland, and a resident of Edinburgh, Scotland, have invented certain Improvements in Apparatus for Heating Air for lherapeutic or other Purposes, of which the following is a specification.

My said invention has forits object to combine or arrange portable apparatus for conveniently and expeditiously producing currents of air or gas of any required temperature within moderate limits for therapeutic and other purposes, and as an example I may state that when neuralgi cor other pain is due to a cold draft or chill relief is obtainable by directing a suitably-heated current of air upon the affected part.

The apparatus comprises means for imparting motion to the air or gas, combined with means for heating it; and in order that my said invention and the manner of performing the same may be properly understood I hereunto append a sheet of explanatory drawings, to be hereinafter referred to in particularly describing my improvements.

Figure l on the accompanying sheet of drawings is a plan, Fig. 2 an elevation, and Fig. 3 a vertical section, of my improved apparatus. In these drawings the same reference-letters are used to mark the same or like parts wherever they are repeated.

As shown in the drawings, there is a piece of spring-actuated clockwork inclosed in a casing A, and such as is employed for supplying air to some kinds of lamps, the clockwork being wound up by means of a thumbkey 13 and being arranged to drive a fan 0 through a star-wheel D and worm E. The fan 0 and its motor are inclosed in an outer casing F, the bottom of which serves as a stand for the apparatus. The upper end of the casing F is fitted with a lining-ring G, of rubber or other suitable material, adapted to receive the lower open end of a tube 11, preferably of glass, within which a smaller glass tube .T is held. The fan O draws air (or it might be gas) from the interior of the easing F, the air entering the casing through holes K in the bottom part, and the fan propels the air through the inner tube J' and also between I t and the outer tube II, which latter terminates in a nozzle L, suitable for direct ing the current as required. When an electric current is available,the fan may be driven by a small electric motor.

Electricity is employed to heat the air or gas in its passage through the tubes II .T, a coil of fine wire, preferably platinum, and shown by dotted lines ill, being wound on the innertube J, and the ends of the wire M being attached to screw-terminals N, fixed in the outer tube II. External conducting wires 1" are attached to these terminals N, and an electric current is sent through these wires 1 of such a voltage as serves to heat the platinum wire M. The current of air or gas in passing through the tubes II J, as hereinbefore de scribed, becomes heated and emergesfrom the directing-nozzle L. The air may possiblybe electrified in passing over the wire M.

A slight hollow Z is formed in the lower side of the tube II near the nozzle L, in which hollow Z a small quantity of volatile liquid may be placed, the vapor from such liquid mixing with the heated air or gas.

The temperature to which the heated current of air or gas is raised may be modified to suit diiferent cases by means of adjustable resistances, (not shown,) through which the electric current is passed.

The outer glass tube II may be made with the directing-nozzle part L of considerable length in comparison with that part of the modification hereinbefore described, and the inner glass tube .T, with the heating platinum wire M, may be held in that part L. In Fig. 3 the nozzle L is shown as formed on the unbent end of the tube II.

For the purpose of being conveniently held in the hand in a horizontal or other position the casing F may be made without a bottom stand, holes K for admitting air to the interior of the casing being formed in a ring, which may turn with the thumb-key 13.

What I claim as my invention is The herein-described portable apparatus for producing a heated current of air or gas for therapeutic or other purposes, comprising forming part of an electric circuit, and means within the casing for forcing a continuous current of air or gas through the directing and concentric tubes, whereby air or gas passing through the concentric tube and between the outer walls of said tube and the inner walls of the directing-tube is heated thereby, substentielly as specified.

In testimony whereof I have signed my name to this specification in the presence of IO two subscribing Witnesses.

VILLIAM TAYLOR.
